摘要:
A method of forming a sulfur-based cathode material includes: 1) providing a sulfur-based nanostructure; 2) coating the nanostructure with an encapsulating material to form a shell surrounding the nanostructure; and 3) removing a portion of the nanostructure through the shell to form a void within the shell, with a remaining portion of the nanostructure disposed within the shell.

A microbial battery is provided. At the anode, microbial activity provides electrons to an external circuit. The cathode is a solid state composition capable of receiving the electrons from the external circuit and changing from an oxidized cathode composition to a reduced cathode composition. Thus, no external source of oxygen is needed at the cathode, unlike conventional microbial fuel cells. The cathode can be removed from the microbial battery, re-oxidized in a separate oxidation process, and then replaced in the microbial battery. This regeneration of the cathode amounts to recharging the microbial battery.
